How to configure lag on a EOS Switches like securestack B5 for esx teaming nic

[Robert_J]

We try to connect 2 teaming nics on a esxi V6 to a B5 securestack configured with static lag but after connecting the second link we loose our connectivity.
Does anyone has an Idea for our problem ? Is it a problem in the esx ? With an HP switch we can connect the esxi but not with the securestack.

Hi Robert,

you should check if the VLAN configuration of LAG (e.g. lag.0.3) and the physical ports (e.g. ge.2.42;ge.3.42) match. The LAG is configured independently from the physical ports, thus you need to configure the VLANs for the LAG as well. You can use the command "show vlan portinfo port ge.2.42;ge.3.42;lag.0.3" to verify.

It might be helpful to understand some more of the configuration. Does the lag have the proper vlan association? Can you share the relevant parts of the configuration? Given the output you supplied ports appear to be in lag.0.3. I will point at a short article but it seems you got that far.
